Hi, don't know if you remember reading rcr's posts - she designated MLCers as Drop ins [the ones' who stay around constantly and want to be friends] Droplets, who make sporadic contact, and Drop-outs who largely vanish from our lives.

I think Imlin has a permanent thread on the first MLC page What I learned from my h's MLC

It seems that all types of MLcer can return, but by the time they might want to think about it, mostly we have moved on - as you know this process takes a very very long time for most of these people to work through, if they ever have the courage and honesty to deal with their issues after they become aware of the devastation they have caused. I used to be sad I had mostly a vanisher [occasionally popped up to hurl abuse] but now I am glad, I think it helps us to heal not to see them or hear from them all the time.
